1. Numerical prediction of propeller induced hull pressure pulses and noise
Sammanfattning : An operating marine propeller is one of the major sources inducing hull pressure pulses, onboard noise and vibration as well as underwater radiated noise. There are rising concerns of environmental impacts and comfort and welfare of passengers and crews due to these negative effects. LÄS MER
2. The Spider and the Sea : Effects of marine subsidies on the role of spiders in terrestrial food webs
Sammanfattning : The purpose of this study was to identify if terrestrial arthropod predators on Baltic Sea shores vary in their use of marine versus terrestrial food items, and to construct a bottom-up food web for Baltic Sea shores. The inflow of marine nutrients in the area consists mainly of marine algal detritus and emerging aquatic insects (e.g. LÄS MER
3. Baltic shore-lands facing climate change
Sammanfattning : This thesis provides new insight concerning drivers behind differences in arthropod diversity and abundance in Baltic shore ecosystems and how the arthropod communities might be affected when the conditions in the Baltic Sea are altered due to climate change. The focus has been on climate related changes that are unique for coastal ecosystems, especially sea level rise and changes in the inflow of marine nutrients. LÄS MER
4. Marine Propulsion System Performance Beyond the Propulsive Factors
Sammanfattning : The marine propulsion system often operates in the wake of the ship it is mounted on. This implies that the propulsion system affects the flow around the hull, and the inflow to the propulsion system is dependent on the hull shape. LÄS MER
5. Response of marine food webs to climate-induced changes in temperature and inflow of allochthonous organic matter
Sammanfattning : Global records of temperature show a warming trend both in the atmosphere and in the oceans. Current climate change scenarios indicate that global temperature will continue to increase in the future. The effects will however be very different in different geographic regions. LÄS MER
